arrows in zohoshow

I loved this application yesterday, when I was creating a slideshow on a windows machine.
Today I am trying to view it and edit it on a linux machine (ubuntu) (my home machine)
and am having trouble with the arrows.
They now block part of the text and I can not edit them at all, not even to remove them.
I checked, and I have the latest version of Adobe flash - 9,0,48,0.
Is there anything else I should do?
thanks, I hope I can continue to use this application!
